1. Technical Field
The present disclosure relates to support mechanisms, and particularly to a support mechanism used in an electro plasma polishing process.
2. Description of Related Art
In an electro plasma polishing process, a plurality of workpieces is fixed on a fixture, the fixture with the workpieces is then mounted on a support mechanism. The support mechanism is electrically connected to an anode, and then is mounted on a lifting device. The workpiece mounted on the fixture is immersed in an electrolyte solution and electrically connected to a cathode and polished. However, since the support mechanism is electrically connected to a single anode, the power supplied to the workpiece mounted on the fixture is limited, thereby limiting the polishing efficiency.
Therefore, there is room for improvement in the art.
The components in the drawings are not necessarily drawn to scale, the emphasis instead placed upon clearly illustrating the principles of the present disclosure. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.

The second electrically conducting assembly 50 has a structure similar to the first electrically conducing assembly 30, and is mounted on the first side surface 101 adjacent to the other end of the main body 11 opposite to the first electrically conducting assembly 30. One end of a second bearing pole 51 of the second electrically conducting assembly 50 is extended through the fourth sleeve 191, and then is mounted in the third sleeve 181. A substantially middle portion of the second bearing pole 51 is mounted in the fourth sleeve 191.
The third electrically conducting assembly 70 has a structure similar to the first electrically conducing assembly 30, and is mounted on the second side surface 102 between the first electrically conducting assembly 30 and the second electrically conducting assembly 50. One end of a third bearing pole 71 of the third electrically conducting assembly 70 is mounted in the second sleeve 171, and electrically insulated from the first bearing pole 31 by having the first electrically insulating sheet 173, and the other end of the third bearing pole 71 is mounted in the third sleeve 181, and electrically insulated from the second bearing pole 51 by having the second electrically insulating sheet 183. In other words, one end of the third bearing pole 71 is connected to but electrically insulated from the first bearing pole 31 via the second mounting portion 17, and the other end of the third bearing pole 71 is connected to but electrically insulated from the second bearing pole 51 via the third mounting portion 18.
In the illustrated embodiment, the first bearing pole 31 is substantially the same size as the second bearing pole 51, but larger than the third bearing pole 71. The first bearing pole 31, the second bearing pole 51, and the third bearing pole 71 are made of electrically conductive materials.
The positioning assemblies 80 are sleeved on the first bearing pole 31, the second bearing pole 51, and the third bearing pole 71, for positioning the fixtures 200. In the illustrated embodiments, the support mechanism 100 includes three positioning assemblies 80 sleeved on the first, second, and third bearing poles 31, 51, 71, respectively.
The connection assembly 90 includes a first connection seat 91, a second connection seat 93, a third connection seat 95, and three fixing members 97. The first connection seat 91 is mounted on the first side surface 101 at the end of the main body 11 adjacent to the first electrically conducting assembly 30, and is electrically connected to the first electrically conducting assembly 30 by means of or using one of the three fixing members 97. The second connecting seat 93 is mounted on the first side surface 101 at the other end of the main body 11 adjacent to the second electrically conducting assembly 50, and is electrically connected to the second electrically conducting assembly 50 by means of or using another one of the three fixing members 97. The third connecting seat 95 is mounted on the second side surface 102 at the other end of the main body 11 adjacent to the third electrically conducting assembly 70, and is electrically connected to the third electrically conducting assembly 70 by means of or using another one of the three fixing members 97. The first connection seat 91, the second connection seat 93, and the third connection seat 95 are electrically connected to three different outer anodes, respectively. Therefore, the first bearing pole 31, the second bearing pole 51, and the third bearing pole 71 are electrically connected to the three different external anodes, respectively, and are electrically insulated from each other.
During usage, three fixtures 200 are mounted on the first, second, and third bearing poles 31, 51, 71, respectively, and positioned by the positioning assemblies 80. The connecting portions 13 are connected to the external lifting device, and the first connection seat 91, the second connection seat 93, and the third connection seat 95 are electrically connected to three different external anodes, respectively. After supplying current to the external anodes, the support mechanism 100 is moved by the external lifting device, and the fixtures 200 are immersed in an electrolyte solution and the workpieces are electro plasma polished.
In other embodiments, if more power is supplied, more fixtures 200 can be mounted on the first bearing pole 31, the second bearing pole 51, and the third bearing pole 71.
Because the first connection seat 91, the second connection seat 93, and the third connection seat 95 are electrically connected to three different external anodes, respectively, a total power capacity is thereby greater. Thus, polishing efficiency is improved.
In other embodiments, the support mechanism 100 can further include other electrically conducting assemblies, or an electrically conducting assembly can be omitted, as needed.
While various embodiments have been described and illustrated, the disclosure is not to be construed as being restricted thereto. Various modifications can be made to the embodiments by those skilled in the art without departing from the true spirit and scope of the disclosure as defined by the appended claims.
